A first device in a communication network receives from at least one second device in the communication network, a first request for acquiring a token, the token being permission for communicating with a third device. Based on the first request, a device from the at least one second device and the first device as a communication device is selected for providing a communication service to the third device in the communication network; and the token is transmitted to the communication device. The communication device receives the token for communicating with the third device. Other devices receive key information associated with communication of the third device from the first device, and monitor data associated with the communication of the third device.

Systems and methods described herein provide an intelligent MEC resource scheduling service. A network device in a MEC network stores, in a memory, threshold values indicating overload conditions for resource usage by a first MEC cluster; monitors resource usage in the first MEC cluster; determines, based on the monitoring, when one of the threshold values is reached; identifies available resources in a second MEC cluster; and re-directs, based on the identifying, at least some of the resource usage from the first MEC cluster to the second MEC cluster.

Methods for data downloading and a related terminal device are provided, which include, upon receiving a downloading instruction input by a user, determining a target downloading task and determining communication protocols currently supported by the terminal device. The target downloading task can be divided into a plurality of subtasks based on preset ways. At least two communication protocols from the communication protocols currently supported by the terminal device are selected as target communication protocols. Downloading of the plurality of subtasks is based on the target communication protocols.

A method including storing, by a first device in a mesh network, stored connection state information associated with an outgoing communication transmitted by the first device; determining, by the first device, observed connection state information based at least in part on receiving an incoming communication from a second device in the mesh network; comparing, by the first device, the observed connection state information with the stored connection state information; and selectively processing, by the first device, the incoming communication based at least in part on a result of the comparing. Various other aspects are contemplated.

A node performs multi-hop communication. The node includes a relay node determiner that determines a relay node from a plurality of relay node candidates having path information of a path to a master node. The relay node performs relaying. At least when communication frequencies of the relay node candidates are within a predetermined range, the relay node determiner determines the relay node so that a relay node candidate with a higher communication frequency is more likely to be determined as the relay node than a relay node candidate with a lower communication frequency.

Apparatus and methods are provided for cooperative communication for sidelink relay. In one embodiment, a plurality of sidelink relay paths are configured for an end-to-end communication path between two end nodes, a source node and a destination node, with one or more relay UEs. The source node or one or more intermediate relay node(s) within the sidelink relay path performs packet, segment, or radio bearer based cooperative communication at one protocol layer. The cooperative communication includes data duplication and data split depending on one or more factors. In one embodiment, the cooperative communication is supported by the weigh value transmission from the sender to the receiver node within the sidelink relay network. The weight value is statically configured or dynamically carried by an ACP control PDU. In one embodiment, the cooperative communication is supported by the redundant packets or segments removal at the intermediate relay node(s), and/or destination node.

The invention relates to a wireless communication system comprising a plurality of radio devices. Each radio device belongs to one or more radio neighborhoods and is capable of repeating the transmission of the broadcast message regardless of whether the radio device is operating as a router device or as a non-router device. The radio devices belonging to each radio neighborhood are configured to repeat collectively a transmission of a broadcast message a collective target amount of repetitions within each radio neighborhood. Each radio device within each radio neighborhood to which it belongs is arranged to: define a total repetition load value representing a contribution of said radio device to the collective target amount of repetitions of the broadcast message within said radio neighborhood, and decide whether to repeat the transmission of the broadcast message in accordance with the defined total repetition load value. The invention relates also to a method for the wireless communication system, a radio device for the wireless communication system, a method for the radio device, a computer program, and a tangible non-volatile computer readable medium.

Systems and methods for controlling congestion of a data network are provided. An engine round-trip time (RTT) and a fabric RTT for a network flow are determined. An engine-based congestion window size for the flow is determined based on the engine RTT and a target engine RTT. A fabric-based congestion window size for the flow is determined based on the fabric RTT and a target fabric RTT. The smaller of the engine-based congestion window size and the fabric-based window size is selected for use in transmitting a future packet associated with the flow. The target engine RTT is determined based in part on the current congestion window used to transmit packets for the flow and/or the target fabric RTT is determined based on a number of hops packets associated with the flow traverse from a source to a destination associated with the flow.
